Quick question or two (like that's really gonna happen!):

On my 2011 i7 MBP, it sometimes gives me some "issues" such as applications crashing; I see (just for a second or less) something that should have already cleared, or the screen just "pixelates" and then fixes itself. Just tonight, I woke it up from last night, and I see for a second the background I saw when I booted it from the restore disk and ran disk utility, as well as the screen for disk utility, AFTER I had rebooted it back off from the hard drive! It quickly cleared itself up, and now appears normal. Last night, Safari went nuts as in the fans ramped up to warp 10 and this thing really began to throw the heat out. When I quit Safari, it went back to normal. A hardware check reveals "no problems." Thoughts on this?

I have two applications that have/had problems; one I fixed when I removed a buggy add-on, and the other I will seek help through the software company. I suspect I may be stressing the software more than the writers had originally thought.

Also, while I had it booted from the restore disk, and running disk utility, I verified/repaired the disk since it found a few problems, mainly with forks. These appear to have been fixed (from what I can tell). However, and there's the real question, when I run disk utility to repair permissions, it says it is repairing the issues or has repaired it, but when I run it again immediately afterwards, the SAME issues come up again. This happens regardless of whether I boot from the system disk, or the hard drive. Any thoughts on this issue?

These issues have been bugging me, but I don't know if it warrants taking it for a "genius" checkup. Do you guys have any particular things you prefer to run to ensure a clean, long-running, trouble-free system?

More system info: 2011 i7 MBP (as I said before) running 10.6.8, 8 GB ram. 750 GB hard drive, 300 GB available.

If your computer does not have third-party RAM, there may be compatibility issues with the application or a plug-in for the application. If it does have third-party RAM, that may be the culprit.

Flash. Expunge it from your system.

That's normal:

I give software two chances. The third time it misbehaves, it's removed with extreme prejudice. I avoid utilities, interface fixers, most plug-ins, etc. My system is in active use at least 10 hours per day. It has never crashed.

It nevertheless appears that you have a hardware problem.

The pixellated screen is a dead-giveaway.

My best guess is that it's overheating.

If you bring it to an Apple Store, tell them about the pixellated screen and the ramped up fans, they should take it overnight for diagnostics. If the "genius" give you any attitude, demand both a Service Diagnostics test and a stress-test.

What does the log say?

Thanks for the useful information.

The two applications in question are LibreOffice and Sente. LibreOffice is much more stable since I killed a plug-in for it, and in fact has not crashed since the plug-in died. No plug-ins were applied to Sente. I will be taking the issue up with the appropriate individuals as that is the best avenue to go.

The explanation for Safari explains much of what I've been seeing with that program. Somehow this doesn't surprise me. It becomes a memory hog if left up and running for too long, taking LARGE chunks of ram for no apparent reason and not relinquishing it unless Safari is closed and restarted. I'll see what I can do with this.

I have not checked the logs (in fact, I forgot about them!). I shall remedy the oversight.

Both 4GB ram sticks came from OWC, so it is possible (but not likely) that there is an issue with them. However, since the crashing issues are restricted to only two programs, it is more likely that the issue is/was with the applications themselves and not ram.

I rely on this machine far too much to immediately take it to the "genius" without making arrangements first. Thanks for the heads up. I may have to repossess the old MBP if the repairs are going to take long.

As I am sure someone would take offense to the rest of my comments, I am most tempted keep them to myself. But, as only one "dancing figure" and "ban sign" would have adequately got the point across, here you go:

No, not necessarily. More than once I have seen RAM issues that affected a single application only. It all depends on an application or process accessing a defective part of physical RAM.

If you still have the computer's original RAM, you may want to try running the system on that RAM only.

I still have it. I'll give it a try and see what happens.

my ban/repost was a joke.

since someone filled a page with them for a repost i made recently.



did you run memtest in single user mode?

Sorry. Misunderstaning sucks. Anyways...

No I haven't tried memtest. In addition to my normal supposedly 8:30-5:00 job, I teach two nights a week (Tuesdays and Thursdays). Tonight I should have some time to check out all the stuff I need to look at. Thanks for the suggestion, and I'll let you know what I find.
